.or nozzle of any-ooe Patented March 3o, 1909 drawn through cocks, faucets or bibbs eln-v bodying turn plug valves controlled by lat-V erally extending exterior handles. In drawing liquid from such cocks, it is, necessary for the waiter or other attendant to utilize ione-hand in holding the'glass or cup be- ;neath the cock while the other hand is ein- `ployed in manipulating the valve operating handle thereof. Much time is fthus con- `vsumed, as the hands must be free of dishes or otherarticles to enable the attendantV to .draw the liquid, and again there is considerablewaste in the form ofdrip from such cocks, by reason of the comparatively long distance between the plug valve of the cock andthe end thereof. v The device ofmy invention is adapted to 'be coupled to the lower .or discharge end of such cocks and forms a short downward con-A tinuation thereof and contains a vertically moving automatically closing check valve provided with a horizontally dis osedl lifting bar adapted to be engaged an lifted by the glass or'cu l In the drawings, 1 is the discharge end li or liquid discharge pipe, usually formed with the dowg turned or vertical extremity. These cock such as commonly .employed on water coolers, coffee urns, etc., have exteriorly smooth downturned discharge ends or nozzles.

The automatic faucet of my invention is at its upper end adapted to be. coupled to and form a. vertical downward continuation of the dischar e end of the cock 1. The hollow or, tube ike casing of my faucet is formed in sections. For instance, I show the same composed of the main body or section 2, the valveseat section l3, and the discharge f end 'or nipple section 4.

discharge opening or 'nozzle' At lits upper end the faucet casing is formed with an exterior screw thread 20, meshing with the internal threads in the lower end of a coupling union'or com ressing sleeve 5, receiving and longitudlnally adjustable on the upper end of the casing and adapted to receive the discharge end of the cock l. At its upper end, the union 5, is formed with aninternal annular flange 50, at its under side formed 4'with a bevel 51 forming the union with an internal yshouldei. beveled inwardly and upwardly. `A cylin digical gasket or, ring 52, of Vsuitable elastic ""compressible .material such as'mbber comiesl the upper. ends of v3, is of a smaller on the faucet casing to compress the gasket tightly between the upper -edge of casing 2, and the beveled shoulder tightly compress said gasket varound and againstthe cock end 1, with suiicient force to forrn'a tight joint between the faucet and cock and to support the faucet, see Fig.v 2. Thebevel tends to force the gasket inwardly against and completely around the cock end,

and a coupling is thereby formed permitting ready' application or disconnection of the faucet..' y

In' the specific example illustrated,y the lower end lof casing body 2,: is internally threaded, and the vvalve seat section 3, is formed 'with a'n exteriorly threaded reduced end which removably screwsinto the lower end of thecasing body. The bore of section diameter than casing body 2, and 'the upper endedge of the section 3,

forms valve seat 30.

The lower end of valve seat section 3, is usually enlar ed in diameter andinternally threaded to ongitudinally and detachably receive the thread 42 of the usuallyreduced ple 4, which at its lower end 'canbe forme with an eX- ter'ior 4annular flange or shoulder 40. lThe nipple 4, is formed rwith two longitudinal diametri'cally opposite slots 41, closed at their lower ends and opening at their upper ends through the top edge of the nipple.r The slots st-art a distance above theV lower end of the nipple and extend upwardly through the upper end of the nipple", so that the' slots, when the nipple is inoperative position, are closed by thel lower end of the valve' seatl section 3.

In the specific example illustrated, I show a -nietal.f ballvalve 6, movable vertically' in casing 2, andadapted to rest on'yalve seat 30, and tightly close 'the casing against passage of liquid through section 3. This valve is provided withv and adapted vto be lifted from its seat Vbyff'a lifting rod 7 passing diametricallythrough the nip le 4, with both ends projecting radially and in opposite directions at the exterior of the nipple and "passing looselyl lthrough the slots 41. At

per end of the center o f its length said lifting bar is rigid with a vertical valve stein 8,'to the upwhich the valve is secured.- I usually cast or otherwise form the'lifting bar and valve stem in one piece of suitable metal, and suitably secure the upper end of the valve stem in the lower portion of the valve iii any 'desirable manner, for instance, by threading the up er end of the stem and screwing the saine into a threaded socket tapped radially `into the valve as shown in 51, and thereby" valve can be lifted of the liftingbar is is greater than the vof the cups, glasses or other receptacle by When` cock valveis allowed to remain open,

the weight thereon cup passes from vbelow ranged loosely on 4, supported and resting on the shoulder 40,

Fig. 1, so that the valve, stem and bar be rigid withv each other with, tlieweiglit of the bar and. stein always on'v the valve.- If

so desired-the upper end of thevalve can `be formed with a screw ygroove or socket 60, to permit rotation of driver receiving theY valve to unscrew the same from lthe stem lifting bai- Vfrom the casing, when the nipple 4, has been unsci'ewed from the casing section 3, so that the liftino` bar can be slipped from the nipple throng the slots 41.

Sato permit.' removal of the valve and its the open ends of- The valve is normally held to its 'seat by 'l 4 gravity,'see Fig. 1, and the slots 41 are ,of such inovenient ofthe lifting valve and vpermit flow of casing and nipple. The lifting bar can be raisedl as shown in Fig. 2, by engagement with the upper edge 'of the like, and the arrangement issu'ch that the from itsjseat if either end elevated,by reason of the rigid fornation of the valve, stein and bar. Vthen the valve' is lifted'by raising one endonly of the bar, the oppositeportion of the bar. engages the'elosed lower which the bar rocks. The length of the bar diameter of the open end which the bar is adapted to .be lifted. the, faucet .has been applied to the cock, the

ut can be closed when it is necessary to repair or cle'a'ir the faucetor for other reasons.

The waiters can quickly till .i'gla ssor cup byutilizing only one `hand in raising the cup to lift the 'bar and valve, and when the desired amount of liquid is drawn, the valve.

will instantly close on removal; ofthe glass. Furthermore, waste by drip will be reduced to vthe minimum by reason of ,the quick re'- iurn' movement of the check valve caused vby and form thereof, y and the comparatively short distance from the check valve to the end therein, whereby will ordinarily completely drain before the the saine.

discharge opening oithe-casing, and the` absence of obstructions the casing below'the valvev so length as to permitsufiicient "vertical" bar 7, to raise'the liquid Vthrough the end of the opposite slot 41 which forms the fulcrum on 95 lt is ,sometimes desirable to lock or hold j the valve inelevated or open position for certain purposes. In the specific example illustrated, I illustrate a the exterior of the nipple roughenedor milled surface 190 yby which the sleeve can be turned or oscillated on the nipple.

Q Thesleeve 9,- is recessed at its op osite portions," at"91, opposite the slots 41 1n the nipple so 'that said recesses 91 w1ll reg1ster -with the slots. The recesses open through the top edge'of the sleeve, and the lifting bar 7, projects through the' recesses. Each recess `91, at one end is in height equal to or greater than the length of each slot 41 so that vwhen the sleeve is at its limitof'movement in one direction the lifting bar is fiee to move its free ystroke and can drop to its limit of downward movement with the valve in seated closing position. The door of each recess forms a cani edge 92 rising on curved 'lines from the deep end of the recess toward the opposite end thereof, and' these cam edges are so formed that when the sleeve is turned in one direction, to the right, in

Figs. 3 and4, the lifting bar will be elevated by engagement with the cam edge and when kthe sleeve reaches its limit of movement in lsaid direction the bar will be held -in elef vatedposition, see Fig. 4, holding the valve in open position. Then the sleeve is turned to its normal position the lifting bar and valve will drop by gravity to their normal lowered position. y

Having thus described my invention, what I claim las new and desire to secure by Let- :ters Patent of the United States is movable checlevalve, said casing having 1.
